Redescription

Female ( Figs 28–33 )

LENGTH. 1.9 mm.

COLOR. Head ( Figs 28–30 ) dark with metallic purple luster on temple and occiput, and lower face and gena mainly with metallic green luster; ocelli dark brown; maxillary and labial palpi brown to dark brown. Antenna ( Fig. 30 ) with scape yellowish-brown and pedicel dark brown with metallic green luster, flagellum dark brown. Pronotum ( Fig. 31 ) brownish-yellow, and posterolateral corner dark brown anterior to spiracle. Mesoscutum ( Fig. 31 ) light yellowish-brown except anterior convex part of medial lobe with golden-green metallic luster. Scutellar-axillar complex ( Figs 31, 32 ) brown with goldengreen metallic luster. Tegula, acropleuron and prepectus light yellowish-brown ( Fig. 28 ). Legs ( Fig. 33 ) yellowish-brown except tibiae light yellowish-brown. Metanotum and propodeum ( Fig. 32 ) brown with margins slightly darker. Gaster ( Fig. 28 ) dark brown with base pale yellow.

HEAD. In frontal view ( Fig. 30 ) about 1.27 × wider than high; in dorsal view width 1.4 × length, hind margin concave; in lateral view about 1.2 × higher than long. Eye height 1.71 × eye length in lateral view, distance between eyes below 2.1 × distance between eyes above; malar space 0.45 × eye height; distance between toruli 0.9 × distance between torulus and clypeal edge, and 1.29 × distance between torulus and orbit; frontovertex as wide as eye. OOL: POL: LOL = 2: 9: 5. Vertex ( Fig. 29 ) reticulate, frons imbricate; lower face ( Fig. 30 ) coarsely reticulate-rugose with short translucent hair-like thin setae, medially angulate; gena strigose; parascrobal region reticulate-rugose to coriaceous upper portion, scrobes and interantennal region ( Fig. 30 ) reticulate-rugose, interantennal region with some white slender lanceolate setae. Scrobal depression ( Fig. 29 ) with scrobe deep, lateral margin angulate, separated from anterior ocellus by distance 1.6 × diameter of anterior ocellus. Lower orbit in line with ventral margin of torulus. Antenna ( Fig. 30 ) with scape not extending to anterior ocellus, relative length (width) of scape 31(6); pedicel 9(5); anellus 3(4); 1 st to 7 th funiculars: 8(5): 8(5): 7(6): 7.5(7): 7.5(7.5): 6(8): 6(8); clava 21(9).

BODY. Pronotum in dorsal view acute-triangular, very finely coriaceous, concave postero-medially, four short setae at anterior margin of collar and only one seta posteriorly anterior to each spiracle; median groove shallow. Mesoscutum ( Fig. 31 ) with anterior convex part of medial lobe V-shaped, about 0.64 × total length of mesoscutum, coarsely punctate-reticulate and slightly convex, but posteriorly concave part smooth and shiny, with white long setae directed laterally; lateral lobe inclined and finely reticulate. Scutellar-axillar complex ( Fig. 32 ) convex, longitudinally coarsely reticulate; scutellum 1.63 × longer than wide. Acropleuron ( Fig. 28 ) with fine longitudinally aligned coriaceous sculpture, anterior portion almost bare. Brachypterous; fore wing ( Fig. 32 ) about 0.6 mm in length, 4 × as long as wide, with apex rounded and extending to middle of gaster; basal plate with one dark brown seta; basal cell sparsely setose with much thinner setae than setae of disc; costal cell ventrally with few setae, and dorsally bare; disc with dark setae and brownish infuscation basally and apically of posteriorly tapered hyaline cross-band with much thinner white setae behind marginal vein; SMV extending half-length of wing, MV slightly shorter than submarginal vein, STV and PMV absent.

LEGS. Profemur with ventral margin evenly arched, without tooth. Middle leg ( Fig. 33 ) with spur as long as basitarsus; tibia with apical pegs in a patch, basal four tarsomeres with black pegs on each margin. Hind leg ( Fig. 33 ) with basitarsus as long as following four tarsomeres combined.

GASTER ( Fig. 28 ). Shorter than mesosoma; ovipositor sheath exserted for distance equal to length of syntergum.

Notes

Only one unlabeled female, here interpreted as the holotype, was found that resembles the original description and illustrations provided for A. huangi . This specimen is entire except for its left funicle and clava.

Remarks

The most important characters of females of this species are as follows: 1) head in dorsal view with width 1.43 × length; 2) clava slightly longer than the length of apical three funiculars ( Fig. 30 ); 3) fore wing only extending to middle of gaster ( Fig. 28 ); 4) mesoscutum with anterior convex part of medial lobe triangular, 0.64 × total length of mesoscutum ( Fig. 31 ). Females resemble those of A. meilingensis , but are differentiated by the characters discussed under the latter species. In the key of Kalina (1981), A. huangi keys out to A. brevipennis Ashmead, 1904 and A. gastropachae Ashmead, 1904 . However, females of A. brevipennis have the head in dorsal view 1.84 × as wide as long and the clava is shorter than the total length of the apical three funiculars ( Kalina 1981), whereas in A. gastropachae the anterior convex part of the medial lobe of mesoscutum is 0.56 × the total length of the mesoscutum and the head in dorsal view is 1.96 × as wide as long ( Kalina 1981).
